Belfast Castle J3279 : Belfast Castle was built between 1868 and 1870 for the Marquis of Donegall. The practice of Lanyon, Lynn and Lanyon were the architects but John Lanyon seems to have been the one who produced the design. It and the surrounding estate probably represent the swansong of the aristocracy in the face of the growth and ascendancy of the wealthy manufacturers, merchants and bankers emerging from expanding industrial Belfast. It was presented to the city in 1937.
